CONVENIENCEThere are no contracts to sign or monthly fees to pay; once you buy it you own it with nothing more to pay to operate it. The system is very easy to set up yourself and doesn't require any installation, only a power outlet and a phone jack. And, when your system is up and running you can program it to call your most trusted family members and friends or 911 to respond to any help alert rather than trusting a company to make decisions for your loved ones. Keep the protection of your family in the hands of family.
